CN201402677Y - Lighting-resistant optical fiber composite overhead ground wire - Google Patents

Abstract

The utility model discloses alighting-resistant optical fiber composite overhead ground wire, which comprises an optical fiber unit which uses stainless steel tube as a sleeve and a metal wire which is stranded outside the stainless steel sleeve, the structure of the metal wire is that a zinc plating layer is arranged outside the steel wire. The structure of the metal wire stranded outside the stainless steel sleeve is that the zinc plating layer is arranged outside the steel wire, the specific heat and the melting point of the zinc are low; when the ground wire is struck by the lightning, thegenerated heat is easy to distribute; therefore the zinc plating steel wire is not easy to break, and the ground wire is not easy to damage.

Description

Anti-thunderbolt Optical Fiber composite overhead Ground Wire

Technical field

The utility model relates to a kind of overhead ground wire of transmission line, especially anti-thunderbolt Optical Fiber composite overhead Ground Wire.

Background technology

The Optical Fiber composite overhead Ground Wire of existing transmission line is twisted metal wires and making outside the fiber unit of making sleeve pipe with stainless steel tube generally, metal wire is generally aluminium alloy wire or aluminium-clad steel wire, the aluminum metal lines of its outsourcing was struck off easily when this Optical Fiber composite overhead Ground Wire was met thunderbolt, caused ground wire to damage.

Summary of the invention

In order to overcome the deficiency of the Optical Fiber composite overhead Ground Wire that has transmission line now, the utility model provides a kind of anti-thunderbolt Optical Fiber composite overhead Ground Wire, can improve anti-thunderbolt performance, the useful life of extended fiber composite overhead ground wire.

A kind of anti-thunderbolt Optical Fiber composite overhead Ground Wire that the utility model provides comprises fiber unit and the outer stranded metal wire of stainless steel sleeve pipe of making sleeve pipe with stainless steel tube, and the structure of metal wire is the outer plating zinc layer of steel wire.

The beneficial effects of the utility model are: because the structure of stranded metal wire is the outer plating zinc layer of steel wire outside the stainless steel sleeve pipe of the present utility model, and the specific heat of zinc and fusing point are lower, the heat that is produced when ground wire is subjected to being struck by lightning distributes easily, so zinc-coated wire is difficult for being struck off, ground wire is just not fragile.
